How to add view count in Cloud Firestore?

I am building a post website and I would like to implement the functionality to add a view count to each post. I think it should be considered with my backend, which is Cloud Firestore.

Does anyone know how to do this?

If you need to increment a counter each time a post is viewed, then you should create a document in which you should add a property of type number like this:

Firestore-root
  |
  --- data (collection)
        |
        --- counters (document)
              |
              --- $postId: 125

The name of the field should be the post ID and the value should be a number. Each time a post is displayed you should simply increment this value. Since you always need to increment the number by one, there is no need to use transactions but an increment operation.
